If you have a 2003, 2004, 2005 or 2006 Mercedes E55 AMG chassis code W211 with Airmatic suspension, you can’t simply bolt on coilovers like BC Racing without any modification. Because the Airmatic models do not have a spring seat in the rear lower control arms, the LCAs must be replaced with an OEM Mercedes control arm made for steel spring suspension. These parts are available at reasonable cost from salvage yards or dealers.
